TROLLEY-WIRE COUPLING- Specification of Letters Patent.

Patented Sept. 26, 1905.

Application filed November 20, 1903. Serial No. 181,964.

To all whom it may concern.-

Be it known that I, EDWARD MILLET LESLIE, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Trolley-Wire Couplers, of which the following is a specification.

In the drawings, Figure l'is a top plan view, and Fig. 2 a longitudinal section on the line 2 2 of Fig. 1.

A represents the tubular body of the coupler, which is provided with a slot and boXes or bearings a, in which are pivotally mounted toothed cams B, adapted to engage and hold the trolley-wires, the cams being mounted in reverse position relatively to each other.

The operation is as follows: The cams are preferably, though not necessarily, thrown out of operative position, the wires inserted, the cams thrown into engagement therewith, and the clamps released. The teeth of the cams engage the Wires, and the greater the pulling strain upon the wires the greater is the grip of the cams. v

It is obvious that the wires may be inserted without throwing the cams out of operative position, in which case the operation of the cams is purely automatic.

I claim as my invention In a splice of the character described, the combination with a tube having a longitudinally-extending slot at the center thereof, and pins extending through the ends of the slot; of oppositely-arranged dogs pivotally mounted upon the pins and having curved toothed working faces, said dogs being within the slot and normally projected by gravity into the interior of the tube.
